Pipeline Field Round API 5L X56M PSL2 Welding Black Pipe
ERW steel pipes are made from rolled metal, or skelp, by welding and shaping. The seams are electrically welded. The end of the pipe is cut at right angles. ERW pipes undergo a special electromagnetic control of seams, volumetric heat treatment, and hydrotesting.
An advantage of ERW pipe is that no fusion metals are used and the weld seam cannot be seen or felt. That’s opposed to double submerged arc welding (DSAW), which leaves behind an obvious weld bead that must then be eliminated depending on the application.Welded pipe manufacturing techniques have improved over the years. Perhaps the most important advancement has been the switch to high-frequency electric currents for welding. Prior to the 1970s, low-frequency current was used. Weld seams produced from low-frequency ERW were more prone to corrosion and seam failure.Most welded pipe types require heat treatment after manufacture.
ERW pipes are most actively used to solve the following tasks: transportation of water, oil, gas, and other media with varying degrees of aggressiveness and reinforcement of various structures in the construction industry
